The following extended example may make the usage clearer; 

<?php

// Create two timezone objects, one for Taipei (Taiwan) and one for

// Tokyo (Japan)

$dateTimeZoneTaipei = new DateTimeZone("Asia/Taipei");

$dateTimeZoneJapan = new DateTimeZone("Asia/Tokyo");



// Create two DateTime objects that will contain the same Unix timestamp, but

// have different timezones attached to them.

$dateTimeTaipei = new DateTime("now", $dateTimeZoneTaipei);

$dateTimeJapan = new DateTime("now", $dateTimeZoneJapan);



// NOTE: $dateTimeJapan is not used further in this example



// Calculate the GMT offset for the date/time contained in the $dateTimeTaipei

// object, but using the timezone rules as defined for Tokyo

// ($dateTimeZoneJapan).

$timeOffset = $dateTimeZoneJapan->getOffset($dateTimeTaipei);



// Should show int(32400) (for dates after Sat Sep 8 01:00:00 1951 JST).

print("Number of seconds Japan is ahead of GMT at the specific time: ");

var_dump($timeOffset);



print("<br />Number of seconds Taipei is ahead of GMT at the specific time: ");

var_dump($dateTimeZoneTaipei->getOffset($dateTimeTaipei));



print("<br />Number of seconds Japan is ahead of Taipei at the specific time: ");

var_dump($dateTimeZoneJapan->getOffset($dateTimeTaipei)

     -$dateTimeZoneTaipei->getOffset($dateTimeTaipei));



print("<hr />");



?>



Number of seconds Japan is ahead of GMT at the specific time: int(32400)

Number of seconds Taipei is ahead of GMT at the specific time: int(28800)

Number of seconds Japan is ahead of Taipei at the specific time: int(3600)
